it's mainly abt the 'bigger picture' which the govt increasingly paints on a yearly basis - ie. more foreign workers/talents, higher gdp, improving local economy.
employers, foreign or locals, thus have more choices in the form of lower wages, but yes, you are right that there might be higher total costs ie. retraining, redeployment, and lower productivity to boot! sometimes, i do wonder why the heck the various govt agencies are promoting local entrepreneurship or enticing me to join some sme govt schemes - all in the name of creating job opportunities? i mean, huh?
in recent years, i'd find that the local employees, however hardworking or talented, are getting more and more disadvantaged whenever they get compared to the lesser talents coming in from philippines and india - specifically supposingly profitable industries such as info-tech, pharmaceutical and banking. for construction, even more competitive, as the hq usually deploy their homeland team from the respective countries. And ssssseriously, if our true-blue local engineers, architects, programmers or marketeers are that lacking in quality, i suppose we need to relook into the manner of courses conducted in the local polytechnics or unis.
all in all, my biggest concern for this country is the gradual reduction in wages of my fellow singaporeans (esp. blue-collar, and the white-collar are feeling it now) in the face of high inflations and growing pool of foreign talents. as long as this is not carefully reviewed, i don't see why our ministers don't get that our birth rate is currently standing at 1.2, for instance.
